Would also agree, urban wetlands here in Canberra are an important drought refuge for many local waterbirds and migratory ones. I was reminded of this when I filmed a Latham's' Snipe in an underpass in Forde last summer (see
https://vimeo.com/144475244).
I note that the water flowing into Yerrabi pond from the surrounding areas is still running clear - the reed filled drains and smaller ponds, often great crake/snipe etc. habitat, installed in its catchment seem to be doing their job, in spite of all the
recent rain.
